Male infertility is a condition in which a man is unable to make his female partner pregnant due to issues related to his reproductive system. Infertility affects approximately 10-15% of couples worldwide, and male factors contribute to about 30-40% of infertility cases. As per experts at an infertility clinic in Bangalore, here are the causes, treatment options, and success rates of male infertility in detail.
Causes of Male Infertility
There are various causes of male infertility, which can be categorised into three main types: pre-testicular, testicular, and post-testicular causes.
- Pre-testicular causes – These causes relate to hormonal imbalances or other medical conditions that affect the production of sperm. Some examples include hormonal disorders such as hypogonadism, certain medications, and chronic illnesses like diabetes or liver disease.
- Testicular causes – These causes have an association with the problems of the testicles, which are responsible for sperm production. Testicular causes of male infertility include genetic conditions like Klinefelter syndrome, undescended testicles, infections such as mumps, and testicular trauma.
- Post-testicular causes – These causes relate to issues with the transport or ejaculation of sperm. Examples of post-testicular causes include obstructive azoospermia (blockage in the reproductive tract that prevents sperm from reaching the semen), ejaculatory disorders, and surgeries such as vasectomy.

Treatment Options for Male Infertility
The treatment options for male infertility depend on the underlying cause and severity of the condition. Some common treatment options include:
- Medications – Hormonal imbalances can often be treated with medications, such as testosterone replacement therapy for hypogonadism. Your doctor may prescribe antibiotics to treat infections that affect sperm production or function.
- Assisted Reproductive Techniques (ART) – ART includes various procedures that help couples achieve pregnancy by manipulating sperm and eggs outside the body. Examples of ART procedures for male infertility include in vitro fertilisation (IVF), intracytoplasmic sperm injection (ICSI), and sperm retrieval techniques such as testicular sperm extraction (TESE) or percutaneous epididymal sperm aspiration (PESA).
- Surgery – Your fertility specialist may recommend surgery to correct anatomical abnormalities or remove blockages that are causing infertility. For example, surgeries such as varicocelectomy (removal of enlarged veins in the scrotum) or vasectomy reversal (reconnecting the vas deferens after a vasectomy) can help improve sperm count and motility.
- Lifestyle Changes – Making certain lifestyle changes can also improve male fertility. For example, avoiding smoking, reducing alcohol and drug use, maintaining a healthy weight, managing stress, and avoiding exposure to environmental toxins can help improve sperm quality and function.
Success Rates of Male Infertility Treatments
The success rates of male infertility treatments vary depending on the underlying cause, the type of treatment used, and the overall health of the couple. In general, ART procedures such as IVF and ICSI have higher success rates compared to other treatment options. For example, the success rate of IVF ranges from 30-50% per cycle, depending on factors such as the age of the female partner, the quality of sperm and eggs, and the expertise of the fertility clinic. ICSI, which involves injecting a single sperm directly into an egg, has higher success rates compared to conventional IVF in cases where there are severe male factor infertility issues.
Surgical procedures such as varicocelectomy or vasectomy reversal can also be successful in improving sperm count and motility. However, the success rates vary depending on the specific case and the expertise of the surgeon. It is crucial to note that success rates for male infertility treatments may also depend on other factors such as the duration of infertility, the overall health of the couple, and any other underlying health conditions. It’s essential to consult with a qualified doctor.
Male infertility is a common condition that affects many couples worldwide. It can have various causes, including hormonal imbalances, testicular issues, or problems with sperm transport or ejaculation. Treatment options for male infertility include medications, assisted reproductive techniques (ART), surgery, and lifestyle changes. Success rates of these treatments depend on several factors and may vary from case to case. It’s crucial to consult with a qualified healthcare provider to determine the most appropriate treatment plan and discuss the potential success rates.
